ELECTRICOOKER Application filed February 16, 1923, Serial T 0 all 'whom t may commet:

Be it known that I, GronoeHnoLitr'Biw non, a subject .of the Kingot' Great Britain, and a resident o i the city of Ottawa, in the Province of Ontario and .Dominion ot' Canada, have invented certain new and useful Improvements in Electric Cookers or llcating Units, owhichthe following is a speci- -eleiuent A may he mounted, as s hown 1n tication.

This invention relates to improvementsin electric cookers or heating units, such as inig'ht'be used for instance in an electric stove or an electrical heating unit, and the objects of the invention are to provide a simple and ell'ectivc form of unit' that can be readily removed and in which the. hcatf..

ing element itself may be readily detached by sli-dingcontact with the terminals on the more permanent portion or' the base. I

Further objects are to provide a device of this kind that can be used with an electric cookror adapted to be used as an electric heate'il with equal satisfaction and economy in construction. i

A further object is to provide a device of thischaracter that can be turned out in large quantities vand readily marketed.

With these and othe-rol; ]cctsin view, the inventiony consists essentially of the improvedl construction hereinafter described, in detail in the Apresent specification and illustrated by the accompanying drawings.

heating element.

Referring to thedrawings, in which like ing parts in each ligure, and in which:

Figure l is a plan view of an embodiment of the invention..

ed to receive the resistance wires 12 and extending in the manner indicated on the surface ot' the member A, the wires being supported and protected by cross lugs or bridges l2. 123 are slidable contact pins in sockets il in the hase l0 between the heat- ,ing element and said base.

-l is a cover or lid in which thcheating .Figure :2, the element being reversed in po-v sitionA an'd secured lo the cover by means of bolts 15 extending through the cover and having nuts extending in recesses 16 in the member Contact plus 13 of the heating clement project'into an opening 18 provided in' the cover into which the usual electric connecting plug may be inserted. The material 'used may be of any suitable kind and preferablyplastic.

lil is a suitable handle pivotally connected to the cover. This cover is here shown as provided with supporting legs 20 adapted when not in use to 'be folded beneath the cover, as shownin Figure 7, by being pivotally mounted at 2l. The cover may also he used without these legs or otherwise.

9,2 are projecting lugs formed on the base .l0 a'nd adapted to receive and support a suitable casing member thereon designed to. form a cooker or for any other purpose that may be-required, in combination with said base. v g

- From the foregoing, it will be seen that I have provided an interchangeable heating element-that can be used with an electric cooker or otherwise. To make a perfect cookerwith this interchangeable heating element, it is only necessary to provide a suitable ormed casing adapted to tit on the supporting lugs of' the base 10 having the heating elementA therein. yThis casing is then provided with a suitablecover or lid B, as illustrated, in which another heating ele# ment A is fitted but-f-imreversed form, as illustrated, when the. electric 'oven or cooker is then complete.

F or ordinary cooking b electricity, it is only necessary to use the ase provided, as shown in Figure 4, With my heating unit A., to form an electric stove. l

To provide a readily transportable heater for rooms or otherwise, I use the lid l, as hcrcillustrated, with my heatingmunit reversed and iittell therein, the lid being provided with suilablc supporting means which, when not in use, can be folded. The lid is also provided with a handle for carrying it about when converted'into a heater.

'It will thus be seen that I have provided, as claimed, a simple and effective form of V'interchangeable unit that can be readily duplicated and removed and in which the heating element itself may be readily detached tlirou-gh sliding contact with the terminals on the more permanentportion of the base.

As many changes could be made in the above construction and many apparently widely dili'erentl embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all mat ter contained in the accompanying specifi- -house and support the heating unit,` casing supporting means on the receiving member, and collapsible supporting mea-ns for the receiving member, and a second receiving member 'adapted to form a lid and designed to house the heating unit in an invcited position therein. i

2. An electric heater of the character. 'described comprising a heating unit, a recei v.

ing member adapted to house and support the heating unit, casing supporting means on the receiving member and collapsible supporting means for the receiving member, a second receiving member adapted to form a lid'and designed to house the heating unit in an inverted position therein, and collapsible handling means for said second'receiving member.

3. An electric heater of the character described comprising, in combination with a heating unit, a pair oi receiving members, o ne of -said members being formed with aYV recessed centre having a flange therearound adapted to receive and support the heating unit, a flange on the outside of said mei ber adapted to support a casing, and

rting legs for said member adapted llapse therebeneath in folded position, the.;l ther of said receiving members being designed to form a cover or lid to receive therein a heating unit in inverted position, and'collapsible handling means for the second receiving member.

4. In an electric cooker of the character described, a heating'unit provided with a heating element, a pair of receiving members adapted respectively to form a stand and a cover, means formed on vthe outer periphery of one of said members designed to supportl a casing whereby a cooker is formed, and means including spaced contact pins for supporting and retaining Lthe heating unit innormalposition in oneof the receiving members, means -for securing'and supporting the heating element .in normal position in one of said receiving members,-

I'neansfor securing the heating element in inverted position inthe other or lid receiving member, contact pins carried by the heating unit designed to engage `with recesses in 'saidi'eeeiving members, andjcolmeans-for the other receiving member.

5. vIn an electric heater of the character described, the combination with .a heating unit, of a pair of 'receiving members adapted respectively to form a stand and a lid, and provided With'means for supporting a casing, and. a reversible heating unit adapted to fit into one of the receiving mem bers in normal position and into the'other receiving member` 1n a reverse position.

6. In an electric heater of the character .lapsible supporting means foi'- one of the I receiving members, and collapsible handlingdescribed, the combination. with abase rei ceiving member adapted to form a stand and formed with casing supporting means, ci' a second receiving member adapted in combination with the first receiving member and a casing to form a lid having collapsible handling means and a reversible 'heating' unit designed to t into the base receiving member in normal positionl'and into the lid-A.

receiving member in reverse position, and

means for retaining the heating unit in position in said receiving members.

1n witness whereof l have' hereunto set my han'd in the presence of a witness.
